The THERMOLITE Reactor Extreme liner is Sea to Summit s warmest knitted sleeping bag liner. If your adventures take you to colder climates, the Reactor Extreme will add plenty of warmth to a sleeping bag. In warmer weather, it can be used a stand alone sleeping bag. The hollow core fibers of the THERMOLITE fabric work like hollow polar bear or caribou fur " along with the knitted structure, this traps plenty of insulating air. Super soft and amazingly stretchy, the Reactor Extreme uses a heavier version of THERMOLITE to provide extra warmth for an incredibly comfortable night s sleep. Use one to build your cooler-weather sleep system and to help to keep your sleeping bag clean, too.
